INTRODUCTION
One of the most powerful aspects of .NET and Windows Forms is data
binding. Data binding is the process of associating user interface
(UI) elements with a data source to generate a visual representation
of data. Two types of data binding are available for Windows Forms:
Simple Data Binding and Complex Data Binding.

Hi,
I'm using a ComboBox, some Textboxes, and a DataGrid to represent a
many-to-many relationship between Person and Course. Each time that I change
the value in the ComboBox (which for now is the OID of Person), the
information of the person matching the selected OID is shown in the Textboxes
(Name, Address, id, etc) and the courses this person is taken are shown in a
DataGrid (course name, price, etc.). This is working well so far, I...

Hi, I'm able to make connection to a server using socket connection.
However, when I send a command string the server just ignores it. All
command string needs to start with "0xF9" at Byte 0. During the run-time
debug, I see it to be "u" with a "~" on top of it. Is that OxF9? Can
someone tell me what I'm doing wrong?
Thanks, Alpha

row, while others multiple rows. I load a bunch of data from the various
tables and add them to a third party grid. With some of the rows, I perform
calculations on some of the rows and all this is loaded into the grid as
well. I am trying to figure out the best way to store all this data so that
it is easier to work with and perform calculations as users edit the...

Hi all,
I'm going to develop an ASP.net page (VB) that allows users to export data
into the zip file. Do you have any sample codes? Please give me the source
codes if you have.
One more question, if we let users export data into Excel file, what is the
good web control we can use ? Do we have to display data on the web page by
binding data with datagrid (or GridView) for this download ?

Overview:
Windows 11 and 10 have less user interface control over operating system update behaviour than previous versions of Windows. In Windows 11 and 10, there is no way to turn off the Windows Update option using the Control Panel or Settings app; it automatically checks for updates and installs any it finds, whether you like it or not. For most users, this new feature is actually very convenient. If you want to control the update process,...

Hello
I'm a network technician in training and I need your help.
I am currently learning how to create and manage the different types of VPNs and I have a question about LAN-to-LAN VPNs.
The last exercise I practiced was to create a LAN-to-LAN VPN between two Pfsense firewalls, by using IPSEC protocols.
